It is apparent that your understanding is as good as any ones... Its just perhaps that you express yourself differently. Scrolling through the many postings soon shows your quest for knowledge. In a related thread (they all are.)You ask of a singlarity... all gravity related... Tommac. Do not stop asking questions for that is the only way your understanding grows more complete. BUT, do remember that this quest for knowledge can never be satisfied completely. The very rules of existence dictate that compliance with the laws of physics. Some times its enough to concede that it just is the way it is because.... Just, because.
